Survey map

At present, with the sustained and rapid development of China, Chinese people’s pockets are getting bigger and bigger, their backs are getting harder and harder, but their hearts are getting more and more "fragile".

According to the random sampling survey of People’s Forum magazine, 45.1% of the party and government cadres considered themselves as "vulnerable groups". White-collar respondents reached 57.8%; Intellectuals (mainly employees of universities, scientific research and cultural institutions) accounted for 55.4% of the respondents; The online survey shows that as many as 70% think they are "vulnerable groups". Why do party and government cadres, white-collar workers and other "elites" feel "weak"? The existence of this universal emotion and the reasons behind it deserve further study.

In addition to extensive investigation, People’s Forum Magazine also invited many well-known experts to conduct in-depth discussions from multiple angles and levels:

For example, with the widening gap between the rich and the poor and the income gap in society, people have a sense of relative deprivation through social comparison.High house priceAnd the pressure of inflation has intensified this sense of deprivation.

For example, the relative concentration of power and capital leads to the formation of social exclusion system, which leads to the social phenomenon of "winner takes all" and "the poor get poorer", and the public mentality is inevitably unbalanced;

　For example, with the rapid transformation of China, the social strata are also rapidly divided, and the internal differentiation of any group and those in a relatively weak position will form a "weak mentality";

　For example, in some institutional designs, there is a lack of universal respect and protection for individual rights. Such institutional arrangements and the weakening of civil rights will inevitably form a "mutual harm" society;

　For example, vulnerability and marginalization are closely related to the changes of social values, and the criteria for judging success have long been changed into the amount of money or the size of power.

　… …

　What needs to be emphasized is that China is currently in a period of rapid transformation, with profound changes in social structure and profound adjustment of interest pattern, and the edge and center, weak and strong, mainstream and edge will constantly change. However, the phenomenon of unfair marginalization and weakness caused by institutional barriers, lack of rights and other reasons deserves our high vigilance. In this issue, experts put forward many countermeasures and suggestions.

Investigation description

With the rapid development of China, Chinese people’s pockets are getting bigger and bigger, and their living standards have generally improved. However, material wealth has not brought spiritual prosperity. On the contrary, more and more people feel that they have become "vulnerable groups", such as white-collar workers, journalists and university professors, and even many officials call themselves vulnerable groups.

Some glamorous groups Why do many people have the same "weak" feeling? How many people feel "weak" under the condition of rapid social transformation? What is the degree? What is the reason for it In order to have a clear and objective understanding of these issues, People’s Forum Magazine conducted a questionnaire survey with a total of 6,235 people, specifically:

First, different groups of random sampling questionnaire survey. Party and government cadres, intellectuals (mainly employees of universities, scientific research and cultural institutions) and company white-collar workers were selected to conduct the survey. The effective survey numbers were 280, 213 and 325 respectively.

Second, the People’s Network and the People’s Forum Network launched an online questionnaire, with 5417 netizens participating.

On the basis of obtaining a large number of first-hand data and interview materials, the People’s Forum questionnaire survey center combed and synthesized according to statistical principles, and made a comparative analysis of the main options.

The "weakness" of elite groups is unexpected.

45.1% of the party and government cadres, 57.8% of the white-collar workers in the companies and 55.4% of the intellectuals considered themselves "vulnerable groups".

In the eyes of ordinary people, party and government cadres, intellectuals and company white-collar workers should belong to the elite, not the traditional vulnerable groups, but according to the random sampling survey results of the People’s Forum questionnaire survey center, 45.1% of party and government cadres consider themselves "vulnerable groups"; White-collar respondents reached 57.8%; Intellectuals (mainly employees of universities, scientific research and cultural institutions) accounted for 55.4% of the respondents. This result shows that with the gradual improvement of the social security system, although the traditional "vulnerable groups" are decreasing, the number of people with "weak psychology" or "weak feelings" has not decreased correspondingly, and even has a tendency to spread to some extent.

Why do so many people in the "elite class" consider themselves "weak"? The people’s forum questionnaire survey center conducted an in-depth interview.

45.1% of the party and government cadres interviewed consider themselves as "vulnerable groups", and their "vulnerable" mentality mainly comes from the following aspects: First, in the face of fierce official competition, strict accountability system and strong network supervision, some officials have become "frightened birds", fearing that they will become targets of public criticism because of doing something wrong or saying something wrong, and they are cautious and treading on thin ice every day; Second, although the reform of the cadre and personnel system is gradually advancing, there is still a phenomenon of seniority in some places, even "hidden rules"Prevailing, many officials" don’t run, don’t send "because they have no background, and they are in the dilemma of" ceiling ",and they can’t be reused and promoted, and become" vulnerable groups "in officialdom; Third, the official business is complicated. It is necessary to have political achievements that can be seen by superiors and popular support projects that can satisfy the people. It is difficult to make a difference. Many officials even have anxiety and feel "weak"; Fourth, the wage income of civil servants in some poverty-stricken areas is limited. In the context of the rapid rise in prices, especially housing prices, they can only "look at the house and sigh".

An official, who asked not to be named, said in an interview with the People’s Forum reporter that the public often pays attention to those officials who hold real power or have leadership positions, but pays limited attention to ordinary non-leadership officials, who are the majority of officials. In the bureaucratic structure, these people actually have very limited resources to mobilize, but when they are dissatisfied with their superiors and work units, they often can’t "jump ship" and walk away, so they often rely on "forbearance".

Faced with the "weak psychology" of officials, some netizens pointed out that the process of officials moving from excessive strength to relative "weakness" is exactly the process of disenchantment of a group. Putting power into a cage has always been the hope of the people. Only when the power is restricted enough can the "weak" officials be truly safe.

A sample survey of intellectuals shows that as many as 55.4% of the intellectuals interviewed consider themselves "weak". After more than 30 years of reform and opening up, although the status of intellectuals has been greatly improved, and they are getting richer economically, compared with some real estate agents and invisible corrupt officials who are rich and famous, many intellectuals "cry weak" and "cry poor" first because they are dissatisfied with their own situation, and this dissatisfaction is obtained through comparison. Facing the current marriage of economic capital (wealth) and political capital (power), For example, A Yi, an associate professor at Peking University, once complained about his salary in his blog, claiming that the salary made people "unable to live" and was supported by many well-known professors.

Many university teachers said in an interview with the People’s Forum reporter, "Our heads are rich, but from an economic point of view, we are out and out ‘ Vulnerable groups ’ " .

Secondly, the "weak psychology" is particularly strong among intellectuals in basic and unpopular disciplines. Their teaching and research tasks are very heavy, but their pay is relatively low. Researchers in many popular disciplines such as "Economics" and "Management" have all kinds of opportunities to make public appearances, but for those basic and unpopular scholars, due to the limitation of their majors, such opportunities are relatively few, and many people feel marginalized when they sit on the cold bench and concentrate on learning.

Third, for a period of time, the society respected "knowledge is power", intellectuals were highly respected, and in the wave of marketization, people’s value orientation was also changing. At present, the impetuous society prevails, the evaluation criteria are utilitarian and unitary, and the amount of power and money is often regarded as the only criterion for success, which makes many intellectuals feel disrespected and lonely.

The results of a sample survey of white-collar workers in the company show that 57.8% of the white-collar workers surveyed consider themselves "vulnerable groups". "Doing more and earning less" is the common feeling of many white-collar workers in the interview and investigation. In first-tier cities such as Beijing and Shanghai, white-collar workers are busy with their work and the competition in the workplace is fierce. Moreover, they don’t have stable positions like party and government cadres and university teachers. Facing the endless stream of newcomers and strict performance appraisal, they have to devote themselves to fighting. For this reason, many people are in a sub-health state. For white-collar workers, the unbearable professional pressure is behind the material enjoyment of scenery, and the sense of identity anxiety is behind the decent social status.

Expert analysis pointed out that the current society is in a period of rapid transition, and social classes are also rapidly divided, and some classes lack a sense of stability, especially the white-collar middle class that is currently forming. Under the impact of inflation, the middle class that everyone envied in the past also experienced an unprecedented feeling of "weakness". Some experts pointed out that there is division and competition within the middle class at present. In the process of doubling the average wage level, some people’s income grows rapidly, while others’ income grows slowly. The former can bear higher prices and living costs and is in a favorable position in the competition for resources, while the latter will feel heavy pressure of life.

The middle class, officials and other groups in the collective "cry poor", it is inevitable that people feel melodramatic, but this can not deny the sense of powerlessness of these people in specific situations. In view of the phenomenon that party and government cadres, intellectuals, white-collar workers and other "elites" consider themselves vulnerable groups, experts pointed out that a harmonious society needs a stable expectation, and the lack of rigid systems and fair procedures is the source of insecurity in China. Under the current transformation conditions, this insecurity exists not only in the traditional vulnerable groups, but also in such groups as officials and white-collar workers, which is why different groups have the same psychological background of "weakness". In addition, "weakness" is relative. You are strong in this link, and you may be weak in the next link. However, the prevalence of social injustice and unfairness makes everyone suffer, and the "weakness" mentality naturally spreads.

Sample (Sample), a collection of elements extracted from a population. The same population can extract several samples to form a set, such as 1,000 people from 10,000 Beijing citizens, and there areTwo kinds of extraction methods (without repeated sampling), the set of elements obtained by each extraction method is a sample. In the process of obtaining data, we are often limited to human, material and financial resources, and it is impossible to exhaust all the extraction methods to collect data. Researchers usually get one of so many samples. Therefore, the sample is not unique and uncertain for researchers, but once the data of a sample is collected, its characteristics can be characterized by the collected data. Therefore, the characteristics of the sample are known.

　

A generalized numerical measure that describes the characteristics of a sample is called sample statistics (Statistics), which is some quantities calculated according to the sample data, is a function of the sample. Sample statistics mainly include sample mean., sample standard deviation, sample proportionWait. The number of elements constituting a sample is called sample size or sample size (Sample size), generally usedExpress.

　　BEIJING, June 6 (Xinhua)-On the 6th, the Market Supervision Administration of Shenbei New District in Shenyang issued the "Report on the Investigation of a vendor selling dead crabs as live crabs" in Yurun Seafood Market through its official WeChat WeChat official account, saying that on June 4, 2023, a video number of an online platform released information saying whether there were unscrupulous vendors selling dead crabs as live crabs in Yurun Seafood Market in Shenyang, which deceived consumers and attracted netizens’ attention. The Shenbei New District Market Supervision Administration attached great importance to it, and Yurun Market Supervision Office responded quickly, and immediately launched an investigation on the main market involved and Yurun seafood market. The investigation and treatment results are hereby notified as follows:

　　After investigation, the merchant involved was "Maoge Shangpin Aquatic Products Business Firm in Shenbei New District, Shenyang" at No.21 stall in Frozen Products Zone.

　　When consumers buy flying crabs, the merchants’ language actions mislead consumers. Finally, the anchor bought two flying crabs at the price of 60 yuan/Jin. On that day, the retail price of live flying crabs in the market was 150 yuan/kg, and the price of dead flying crabs was 65 yuan/kg. The anchor bought two dead flying crabs at the price of 60 yuan/kg, and there was no fraud in the price. However, the owner of "Maoge Shangpin Aquatic Products Business Firm in Shenbei New District of Shenyang City" misled consumers through words and actions during the sales period. Law enforcement officers verified with the owner that the situation was basically true.

　　On June 5th, the market organizer Shenyang Gongda Seafood Market Management Co., Ltd. decided to clear the market for "Maoge Shangpin Aquatic Products Business Firm in Shenbei New District of Shenyang".

　　On the same day, Yurun Market Supervision Institute and the market organizer conducted a strict investigation on all merchants in Yurun Seafood Market. All measuring tools in the market were accurate, fair and normal, and no other illegal business practices were found. At the same time, during the inspection, the market merchants were once again given publicity on law popularization and integrity management education.

　　"People can’t stand without faith, and businesses can’t prosper without faith". "Dead crabs are sold as live crabs" damages the rights and interests of consumers and other legitimate operators in the market, which also dampens the confidence of consumers and damages the reputation of the market. Shenbei New District Market Supervision Administration warned all operators: Don’t be lucky, adding "skills" will only lose business; Know how to operate with integrity, so as to achieve your final goal! At the same time, Shenbei New District Market Supervision Administration has always adhered to the "strict" tone, severely cracked down on all kinds of illegal acts in accordance with the law, and will continue to strengthen supervision, resolutely safeguard market order, protect the legitimate rights and interests of consumers, and sincerely welcome the supervision of consumers and all sectors of society.

Census (Census) refers to a one-time comprehensive survey specially organized for a specific purpose, which is used to investigate the total amount of social phenomena at a certain time or in a certain period. It is suitable for collecting some statistical data that cannot or is not suitable for regular comprehensive statistical reports to find out the important national conditions and national strength. For example, the seventh population census in China is to find out the national conditions of China’s total population at 0: 00 on November 1, 2020.

　

Census can not only find out a country’s national conditions and national strength, but also understand and master the situation of human, financial and material resources and their utilization, and provide a reliable basis for the country to formulate long-term plans and policies. The basic requirements of the census are:

　

(1) There should be strict organization and high-quality census personnel;

　

(2) There should be strict time requirements. In the census, the standard time point of the census should be specified, that is, the registered objects should be based on the unified time point specified in advance, and all the survey data must be reflected at this time point;

　

(3) The registration of census should be carried out at the same time in the whole scope of census, so as to ensure the timeliness and accuracy of census data and avoid the delay in data collection;

　

(4) The survey items and indicators must be centralized and unified;

　

(5) The contents and time of similar censuses should be as consistent as possible in previous censuses.

　

In general, the census work should be carried out according to a certain period as far as possible, so as to make a dynamic comparative analysis of previous census data and understand the objective development law. It can be seen that the characteristics of the census are: it is a comprehensive survey with the advantages of comprehensive, detailed and systematic data; It is a one-time special survey with high accuracy and standardization. Due to the heavy workload, long census period and high cost, it is generally not appropriate to hold it frequently.

No one expected that the wind of sharing came so quickly and so strongly, from renting a house, taking a taxi and renting a car, it suddenly swept into the field of charging treasures.

A few days ago, Lei Jun brought Xiaomi Technology, Zimi Technology and Shunwei Capital under his name to share the charging treasure.Just on the 10th of last month, Xiaodian Technology received 100 million RMB financing led by Tencent, plus incoming calls, Hi-power, ANKER Street Power, Didi Charging, Mobao Energy, etc., and there are dozens of shared charging brands.And almost all of them completed huge financing at the same time, and the war of attacking the city and plundering the land was imminent.

Time seems to be back in 2015. After five years of fighting with each other, Meituan and Dianping finally merged, and Didi and Uber also came together hand in hand.

Nowadays, the prospect of shared charging treasure is not clear, and the involvement of many capitals will inevitably accelerate the homogenization of shared charging treasure, and finally inevitably lead to the road of merger.Whoever can provide better service will have a greater chance to stay.

The author deeply visited the shared charging treasures in Shenzhen and experienced the differences in the use of shared charging treasures by various brands. Next, we will make a simple comparison from the aspects of on-site rental experience and use experience.

I. Lending and repayment process and charges

In terms of service convenience, all shared charging treasure operators provide map location services, which are generally distributed in shopping malls, restaurants, cafes, bars and other places with high traffic. Users can accurately find the nearest rental point according to the positioning.

Each rental terminal has different forms. In contrast, the cloud rental terminal is very low in appearance and function. But it is also the only platform that can use charging treasure without paying a deposit.

As far as the use fee is concerned, cloud rental electricity is the most grounded, providing free rental service within 3 hours and providing free charging lines;

The charging standards of other families are basically the same. ANKER Street Power, Incoming Call and Cloud Charging Bar support two platforms: WeChat and Alipay.

Call, cloud charge, sesame credit over 600 points can be exempted from deposit.

Second, the appearance

First of all, it may be to consider the problem of achieving operating costs. These five charging treasures are all made of plastic shells, and they all look relatively cheap.

Among them, ANKER Street Electric is the smallest, easy to hold, and has its own charging short line; The cloud charging bar is the largest in size, and its surface is brushed with stripes, and it also comes with a charging short line;

The design of cloud rental electricity is feminine, and the digital panel is matched with a slim body, giving people a feeling of fragility;

The design style of AUO, which adopts two-stage shell and the edges are not chamfered, is full of masculinity;

In contrast, Caller Technology does not seem to have its own unique appearance characteristics.

Five shared charging treasures are highly contrasted. From left to right, it is ANKER Street Power, Friends Power, Cloud Rent Power, Incoming Call and Cloud Charge Bar.

Thickness comparison of five shared charging treasures. From left to right, it is cloud charging bar, incoming call, cloud rental electricity, friend electricity and ANKER street electricity.

Width comparison of five shared charging treasures. From left to right, it is ANKER Street Power, Friends Power, Cloud Rent Power, Incoming Call and Cloud Charge Bar.

At first glance, these five shared charging treasures are similar to the common charging treasures on the market, but on closer inspection, you will find that there will be metal contact designs at the bottom of the shared charging treasure, ranging from 3 to 5.

This is also their input interface when charging, which is used with the metal contacts on their respective rental machines, avoiding the process of plugging and unplugging the traditional interface and being more convenient to use. Among them, the cloud charging bar and the cloud renting electricity have contacts at both ends, so the advantage of this design is that there is no need to consider the direction when returning the charging treasure.

Third, the parameters and hardware configuration

When you need to rent a charging treasure when your mobile phone is out of power and you don’t have your own power supply, I believe more people are interested in the performance rather than the appearance of the charging treasure. Most people don’t like things that are "shiny on the surface of donkey eggs". After all, emergency use pays attention to practicality and reliability. Only when it meets the requirements of consumers can it really be regarded as a conscience product.

Generally speaking, when we buy a charging treasure, the parameters we usually consider are capacity and input and output power. Of course, for some people, appearance is also indispensable. But for the shared power supply treasure, the most important thing is the capacity and output power, and the capacity is related to whether the receiving equipment can be filled; The output power determines the charging time.

Only when both meet the requirements can users get a better experience. The author made a simple statistics on the nominal parameters of these five shared charging treasures. By comparison, it is found that the capacity of each charging treasure is not large, and the smallest one is only 4000mAh. However, it is not a big problem to supply short-term power to ordinary mobile phones, tablets and other devices when fully charged.

What makes people vomit is their output power. The highest cloud charging bar is 5V2.4A, and the rest is 5V2.1A.. In such a hot background of fast charging industry, as a shared resource, fast charging is not supported, which is contrary to the development trend.Of course, from the operator’s point of view, perhaps it is hoped that the slower the user charges, the better, so that more billing time can be won. After all, the service is provided free of charge within one hour.

In terms of hardware configuration, we only consider the input and output ports and data lines here. In contrast, the cloud charging bar has the best hardware configuration, and this one can supply power to two devices at the same time, but it needs to bring its own charging cable.

butThe spit point here is the friend call and the incoming call, which can be summed up in one sentence: "If you borrow my charging treasure, you must buy my line." In an emergency, most consumers can only be wronged and perfect for this kind of marketing method with strong buying and selling colors.

Moreover, the quality of 10RMB／/charging line is unknown, which makes people think that "I rent a charging treasure, but I earn money from the charging line!"

IV. Measured Output Performance

After talking about the nominal parameters and configuration, let’s test the actual data in the above table. Here, the professional test instrument POWER-Z is used.

After a simple test of the tablet and several mobile phones, it is found that all the shared charging treasures can supply low power to the test equipment. Looking at such test results, do you want to cry when you use a small partner who supports fast charging equipment? The following are the photos of the field measurement for your reference.

　　Zhejiang Online Quzhou August 30th (correspondent Gong Chengliang, Mao Hua, Lan Liangzhong, Zhejiang Online reporter Wu Jiawei, trainee reporter Jin Peng)At 15: 15 on August 29th, Shao Weizhong, director of the police station in Hengshan, Longyou, Quzhou, stood by a roadside in Xiaxishan village, Hengshan Town, National Highway 320, with tears in his eyes, in silence — — The big truck that caused the accident has disappeared, and the police car that was knocked over has disappeared. Colleagues Zhong Wang, Xunhang and Wu Jiansheng have also "disappeared" in nail positioning … …

　　Shao Weizhong felt as if he had had a nightmare, but the brake marks on the ground, the street trees knocked down by the roadside, and the broken windshield of the police car all told him a ruthless fact — — At 16: 10 on the 28th, Zhong Wang, Yan Hang and Wu Jiansheng were hit by a truck when they were in the police station, and they died in the line of duty.

　　A mobile phone that can no longer be dialed

　　"Shao, something is wrong, come and help … …” At 16: 15 on the same day, Shao Weizhong received a phone call from Wang Yuan, the squadron leader of the accident squadron of Longyou Traffic Police Brigade. The other party’s voice trembled. Soon, two police cars arrived at the scene.

　　The big truck was sideways in the middle of the road, with its front half collapsed, next to a police car that had turned sideways into a ditch. Shao Weizhong’s legs went soft at first sight — — As a traffic policeman for 11 years, he has seen all kinds of tragic scenes, but this time lying in the field are his good colleagues and brothers, Zhong Wang, the squadron leader of Hengshan squadron of the traffic police brigade, and Wu Jiansheng, the auxiliary police.

　　Zhong Wang still had a pulse, and he gasped faintly and intermittently. On this day, the sun was fierce, and Shao Weizhong squatted beside Zhong Wang and held his hand hard: "Hold on, hold on!" But when he looked at Zhong Wang’s wide eyes and gradually expanding pupils, he fell like a icehouse.

　　"Quick help, there are people holding up … …” Shao Weizhong was shouted back and helped to carry the police car together. When the car was moved away, a traffic policeman faced down, his hands pressed under his body, his trousers were covered with blood, and his leg was half suspended on the side of the road. The whole person was silent. Shao Weizhong didn’t recognize it. This man is the "younger brother" he has known for more than ten years, and the deputy captain of the traffic police brigade of Longyou County Public Security Bureau.

　　Zhong Wang, Yan Hang and Wu Jiansheng were rushed to Longyou County People’s Hospital for emergency treatment. In that compartment, Shao Weizhong dragged his tired body into a chair, and he still had a glimmer of hope. In the end, what he waited for was bad news … …

　　Not long after, Shao Weizhong received another call. The family of Xunhang couldn’t find his mobile phone. Please ask Shao Weizhong for help. Mobile phone is not only related to the life of Xunhang, but also a thought.

　　Shao Weizhong took six or seven people and came to the scene again. The national road without street lights was dark. When the phone is dialed, there is no bell or bright screen … … Shao Weizhong turned on the flashlight and groped inch by inch in the weeds, pulling in the mud and looking for more than two hours. Near the early morning, snakes and insects appeared, and Shao Weizhong and others had to go home.

　　After a sleepless night, at 5 o’clock the next day, Shao Weizhong called his colleagues to come to the scene again. It was another one-hour search. At 6: 40, an old policeman dug up a mobile phone with a broken screen from the mud on the side where Xunhang was lying.

　　Shao Weizhong’s eyes were red and he thought of the phone call more than a month ago. That day, he called Xunhang and told him to take his family with him to pick grapes. Xunhang sounded a little haggard and said that he would go to the hospital. His wife had a low fever for more than ten days, and he never had time to take her to a big hospital. Shao Weizhong also blamed him a few words, asking him to put his work aside and take his wife to see it for a few days off.

　　However, Xunhang is still hesitant, and he can’t let go of many "burdens" on his body — — Born in 1984, during his 12 years as a police officer, Xunhang stayed in three police stations, went in and out of the legal brigade twice, and began to serve as the deputy captain of the traffic police brigade more than a year ago, not only handling cases but also grasping the legal system construction.

　　Xie Liping, the captain of the Legal Brigade of Longyou County Public Security Bureau, has been working with Xunhang for many years. Although Xunhang was transferred to the traffic police brigade last year, they still often exchanged legal business. The day before the incident, Xunhang also went to Xie Liping’s office to discuss the investigation of a complicated traffic accident case for more than an hour, and finalized the next work measures. Unexpectedly, I saw this good buddy in the hospital the next day. When I saw the swollen face of Xunhang, Xie Liping’s tears fell down. "I didn’t recognize him … …”

　　A reply that can no longer be received.

　　Sleepless all night, there is petiole Hua, the squadron leader of Xiaonanhai Squadron of the traffic police brigade of Longyou County Public Security Bureau.

　　Thirteen years ago, Ye Binghua and Zhong Wang were admitted to the police force and shared a dormitory in the police academy. Even the alarm numbers were connected before and after. Ye Binghua’s alarm number was 557 at the end and Zhong Wang’s was 556.

　　Zhong Wang, 40 years old, has been a police officer for 13 years. He has been working in the criminal investigation brigade of the grass-roots police station and the county public security bureau. In July this year, he was transferred to the squadron leader of Hengshan squadron of the traffic police brigade, and it was only two months since he officially became a traffic police.

　　On the morning of August 28th, Longyou County Public Security Bureau held a county-wide road traffic safety work conference, and Ye Binghua happened to sit next to Zhong Wang. Xiaonanhai Squadron and Hengshan Squadron are next to each other, and they are discussing a joint traffic violation rectification action in Chengbei Development Zone.

　　Only 15 minutes after the meeting, the impatient Zhong Wang called Ye Binghua. "Is there anyone in the squadron? Action? " But at that time, the members of Xiaonanhai Squadron were busy outside, and Ye Binghua had to reply: "We’ll see it in the afternoon."

　　At 15: 14, Zhong Wang’s phone came back again. I learned that Ye Binghua and the team members were diverting traffic at the exit of the expressway. Zhong Wang agreed, "Tomorrow morning, you must send someone to act with me!"

　　In fact, the two agreed to take action in the jurisdiction of Xiaonanhai Squadron. Ye Binghua didn’t expect Zhong Wang to be more attentive than himself. Who knows, the bad news came before the next day.

　　What makes Petiole Hua feel sad is that besides Zhong Wang, his former teammate Wu Jiansheng also died.

　　In Petiole Hua’s impression, Wu Jiansheng, who is 1.67 meters tall, is thin, dark-skinned and wears a pair of black-rimmed glasses. He is a cheerful, self-motivated and responsible man.

　　Ye Binghua has a serious cervical spondylosis. When going out to the police, Wu Jiansheng often asks to drive. When using the police service to investigate and deal with illegal vehicles, he always tries to help. Wu Jiansheng often holds that heavy police pass for hours.

　　Suddenly losing two good comrades-in-arms, Petiole Hua was heartbroken. At 2: 21 on August 29, Ye Binghua, who was tossing and turning in bed, sent a message to Wang Zhong with a nail: "557 calls 556! The joint rectification action is scheduled to start at 9 am. How can you miss the appointment! "

　　At 13: 14 on the 29th, Longyou County Public Security Bureau issued a notice: At 5 o’clock in the morning on August 28th, a traffic accident occurred in Xiaxishan village section of Hengshan Town, Longyou County, 320 National Highway. Huang, a 70-year-old villager from Mohuan Township, fell to the ground after being injured by a tricycle, and the vehicle involved escaped.

　　In the afternoon, Yong Hang, deputy head of the traffic police brigade of Longyou County Public Security Bureau, Wang Yuan, the squadron leader of the accident squadron, drove the "Zhejiang H0616 Police" police car, and Zhong Wang, the squadron leader of Hengshan Traffic Police Squadron, and Wu Jiansheng, the auxiliary police of Hengshan Squadron, drove the "Zhejiang H0611 Police" police car to the scene of the accident for further investigation to find clues. At 16: 07, after the four people arrived at the scene, they parked the police car on the side of the road in turn, turned on the warning lights and the LED screen at the rear of the car to warn them, and looked for clues on the road separately.

　　At 16: 10, the driver Zou Moumou (male, 28 years old, from Suichang) drove the "Zhejiang H29C78" light ordinary truck (without cargo) from Longyou to Jiande along the 320 National Highway. When passing through the road section being explored by the police, he hit the "Zhejiang H0611 Police" police car, and three people, Yun Hang, Zhong Wang and Wu Jiansheng, were hit by the police car that rolled over.

　　After the accident, all forces and enthusiastic people at the scene quickly rescued and sent the wounded to the hospital for rescue. At 21: 00 that day, three men, Xunhang, Zhong Wang and Wu Jiansheng, died in the line of duty after all-out rescue.

　　At present, the driver Zou Moumou has been under the control of the police and the accident is under further investigation. The police are also fully investigating the hit-and-run case that occurred in the early morning of August 28.

　　The NRS brand was first founded by Mr. Qiu Bingzhen, a Hong Kong businessman. Before the return of Hong Kong, the trade between the mainland and Hong Kong was already quite close. As early as Guangdong tried to attract foreign investment with "three benefits and one supplement", a large number of Hong Kong people went north to set up factories in Shenzhen, Dongguan and other places. It was under the attraction of this policy that Mr. Qiu came to Guangzhou to establish the NRS brand. And set up Weiduoer speaker factory in Guangzhou, which is the predecessor of Guangzhou Yasai Digital Electronics Manufacturing Co., Ltd., and is a supporting OEM manufacturer of several top domestic famous brands, with Shanghai Qiaoxiang Trading Co., Ltd. as its general agent in China. NRS not only has advanced production equipment and computer testing system in the world, but also has first-class engineering and technical personnel and well-trained staff. Its extraordinary performance has won unanimous recognition both inside and outside the industry. It was once rated as one of the top ten brands of stage acoustics in China.

　　　　First, the original patented technology — — Obtain a number of authoritative certifications.

　 　　NRS professional sound engineering has been engaged in the design, construction and sales of professional stage, multifunctional conference hall, ballroom, KTV, studio, gymnasium, monitoring system, campus broadcasting and sound engineering for many years. The design philosophy that NRS has always adhered to is to solve the vibration problem that makes the sound deteriorate and distort. With the rapid development and maturity of digital technology, professional digital signal processing technology is also widely used in professional audio products of NRS, such as digital signal processors with high signal-to-noise ratio, active speaker systems with digital processing technology, all-digital front-end effectors, etc. These world-class products bring users higher performance and more convenient use.

　　　　The innovative design adopted by NRS can ensure smooth air flow, so that the overall sound has lower distortion and wider frequency response. At the same time, NRS has a variety of different series of products, which can provide complete product solutions for large theaters, cinemas, performance venues, stadiums, advanced entertainment venues, professional cinemas, wilderness music broadcasting, conference halls, modern electro-acoustic band performances and other professional sound reinforcement fields.

　　　　In addition, the acoustic structure technology of NRS audio used in the box is exclusively developed. Based on the principle of conciseness, high efficiency, making the best use of everything and choosing the best working mode, NRS audio integrates the unique "full-balanced tuning" technical system, and combines physical shock-guiding mechanics and exquisite processing technology, so that it has obtained many professional authoritative certifications. NRS products have obtained CEE- European electrical equipment certification and CE national safety certification, as well as CCC certification of China Quality Inspection Center, and many products have also obtained national utility model appearance patent certificates.

　　　　Second, the quality of seiko — — Win high praise from customers

　　　　Ingenuity, the box materials and workmanship level of NRS audio are the best even if you look at the world. Because of its own advanced equipment and rich manufacturing experience, NRS audio has rich experience and exquisite technology in box processing. The materials used in the box are generous, and the high-quality texture undoubtedly has irreplaceable elegance. Its resonance characteristics similar to those of musical instruments can make the replayed sound quality more musical.

　　　　Because of the cutting, grinding and splicing of plates and the multi-process processing to make a precise box, each process of NRS audio is controlled by hand to ensure the highest quality. Such a genuine and time-consuming job, if it were a foreign brand, I’m afraid the manufacturing cost would be doubled and the selling price would be tenfold.

　　　　The NRS audio produced by exquisite craftsmanship has made the customers who have bought it full of praise, and praised its mellow and loose sound quality. Not only is the bass unit superior in strength, but the delicate sound quality of the mid-high frequency and the soft and gorgeous gloss also show the sense of extravagance that is unique to a group of expensive equipment.

　　　　Many buyers have said that the NRS professional sound system can be adjusted accurately as soon as it is turned on, which shows an open sound stage. The opening sound properly fills the whole venue, and the middle part shows a clear low frequency. Although it is low-key, it is hard to ignore. The sound of NRS professional sound system is clean and transparent, a little warm, not sharp but calm. This combination not only has a high level of resolution, but also has a stable sound thickness, which is not an unattractive trend.

　　　　NRS professional sound system makes the singer’s singing far-reaching and loose, full of energy, with a touch of tenderness, accurate and steady intonation, and the chorus is calm and powerful. However, when playing the symphony, it looks imposing and the overall scale is very grand.

　　　　NRS professional sound system can express all sounds clearly, without any ambiguity, and can listen to each sound separately, but it sounds very harmonious as a whole. Quiet segments can feel the darkness of the background, but in an instant, it is full of ability, quiet and particularly relaxed and leisurely.

　　　　In addition, Andhadhun’s unique technology has achieved clear, transparent and delicate sound quality, and the triple-band connection is smooth and unobtrusive, so that you can hear more details of the sound and get closer to the real sound.

　　　　At present, the typical cases in which NRS professional audio system is used in China mainly include: karaoke system in private rooms of Dongjiang Hotel in Guangzhou, karaoke system in the studio hall and private rooms of Shanghai World Song and Dance Hall, karaoke system in the studio hall and private rooms of Jiazhou Red Song and Dance City in Chongqing, karaoke system in the private rooms of Jinqiao Bay Hotel in Thailand, karaoke system in the private rooms of Jinshi Hotel in Taipei, karaoke system in Taishan Popular Song and Dance Hall, nightclub in Hong Kong and so on. The reason for such a hot sale lies in the high cost performance of NRS.

　　　　Third, many exhibitions — — Be famous all over the world with strength

　　　　Due to the deep cultivation in the industry for many years, NRS audio has accumulated rich experience while having the advantages of material cost and processing cost, and introduced advanced processing equipment to build a world-class audio manufacturing with a production scale. In addition, the application and understanding of acoustic design and technology are more thorough and profound, and NRS products have performed quite well in many trade fairs.

　　　　Professional audio evaluation experts believe that the balance of NRS audio is ideal, there will be no excessive brightness biased towards high frequency, and there will be no dignified emphasis on low frequency, and the sound quality belongs to a neat and transparent style. Full-frequency analysis is also of high standard, which makes the details and overtones rich, so its sound information is abundant, and the sound quality density is sufficient, that is, in exchange for excellent three-dimensional sense. NRS audio has won unanimous praise from all walks of life at home and abroad in the field of stage audio. It was once rated as one of the top ten domestic stage audio brands of HIFI audio and video.

　　　　From February 22 to February 25, 2017, Guangzhou International Professional Lighting and Audio Exhibition was successfully held in the Exhibition Hall of China Import and Export Fair. NRS included the flagship digital mixing system RIVAGE PM10, PM series digital mixer, TF-RACK digital mixer, KB series active speakers, CIS high-end commercial installation system,Newly launched SWP1 series switchesMany new products, such as the fixed installation version of HS series active monitoring speakers and PX series power amplifiers, appeared on the scene.
